Minolta's compact 4x4 TLR — fixed-lens twin-lens reflex on 127 film, waist-level finder, 1959.
The Minolta Miniflex is a fixed-lens twin-lens reflex from Minolta, made in the late 1950s. Unlike the 6x6 Autocord it is a smaller camera built around 127 roll film, shooting the 4x4cm 'super-slide' format. It was produced in modest numbers and is now uncommon, a compact TLR aimed at photographers wanting the twin-lens style in a smaller package.
It is a twin-lens reflex shooting 4x4cm square frames on 127 roll film, giving twelve exposures per roll in this format. The lens is fixed, with a separate taking lens exposing the film and a viewing lens feeding the mirror and ground-glass screen. Focusing is by knob, the leaf shutter sits in the front lens standard, and composition is through a waist-level finder used from above.
The Miniflex suits general and portrait work for photographers wanting a small twin-lens reflex, and its 4x4cm negative on 127 film is larger than 35mm but smaller than 6x6. Its compact size makes it more portable than a full 6x6 TLR. The reliance on 127 film is now a practical limit, as the stock is scarce and costly, and as a fixed-lens design it offers no lens changes.
On a used Miniflex, inspect the taking and viewing lenses for haze, fungus and separation, and check the focus knob for smooth travel. Test the leaf shutter across its speeds, watching for sticky slow speeds. Confirm the film-wind and counter work with 127 film spools, and inspect the ground glass for brightness. Being uncommon, service parts are scarce, so a working shutter and clean lenses matter more when buying.
